CAR CONSTRUCTION.

Application filed October 26, 1923. Serial No. 670,815.

T 0 all whom 'it may Coface/m:

Be it known that I, DAVID HINDAHL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car Construction, of which the following is a specification.

The present invention relates to car construction.

An object of the present invention is to provide a car structure which is strongly reinforced both longitudinally and transversely of the car.

Another object is to provide a car construction involving a self-cleaning center sill for strengthening the car longitudinally thereof, combined with means for strengthening the car transversely.

'A further object is to provide dump car construction having sufficient stiffening means whereby said car is able to withstand the shocks liable to be encountered in service.

Further objects will appear as the description proceeds.

Referring to the drawings- Figure 1 is a transverse sectional view of a dump car embodying the principles of the present invention;

Figure 2 is a view on an enlarged scale of a detail of construction; and

Figure 3 is a top plan view of a section of the car shown in Figure 1.

The numeral 1 indicates a dump car having the side walls 2, 2. Located transversely of the car is the cross tie 3 which may comprise a structural steel member made up of two channels placed with their backs facing one another.

The numeral 11 indicates a center sill which is a fabricated structure including the two channels 5, 5 having their backs facing one another. Said channels 5, 5 may extend practically the full length of the car. The center sill 4 is provided with the cope 6 which will be divided into portions 6', 6, longitudinally of the car by the cross tie or cross ties 3. In the construction illustrated only one cross tie is shown and, for the purpose of this specification it may be assumed that said cross tie is in the transver'se center line of the car. In the construction referred to, two portions 6, 6, of the cope 6 will be provided, one on each side of the cross tie, said portions being spaced longitudinally of the car. The portions 6, 6 of the cope 6 will be united to the opposite sides of the cross tie 3 by means of angles 7, which will be riveted or otherwise secured to. the cope 6 and cross tie 3. As clearly shown in the drawing, the cross tie 3 and cope 6 are located above the center sill 4.-, being mounted upon said sill.

The cope 6 has a cross-section of the shape of an inverted V, the longitudinal ridge thereof being disposed at the uppermost part of the center sill and the sides thereof sloping substantially to the sides of said center sill. The dump doors 9, 9 are pivoted about the axes 10, 10 and form continuations of the sloping walls 11, 11, which are adjacent to the side walls 2, 2 of the car. The pivotal mountings of the dump doors 9, 9 comprise brackets 12, 12.

As will be clear from an inspection of the drawing, the dump, doors 9, 9, when in closed position form closures with the sloping walls 8, 8. When said dump doors are opened, as shown in dotted lines at the right-hand side of Figure 1, lading from the car will be directed centrally' of said car between the car tracks. Each of the dump doors 9, 9, is provided with the intermediate door 13, 13 pivoted to swing about the axis 111. Said intermediate doors 13, 13 are controlled by the chains 15, 15 which in turn are controlled by the shafts 16, 16.

Each of the brackets 12, 12 has the threefold purpose of providing a pivotal mounting for its corresponding dump door 9, forming a bearing for its corresponding shaft 16 and forming a stiftening support for the sloping wall 11. Said brackets 12, 12 are riveted or otherwise securely fastened to the cross tie 3.

It will be obvious from the description above that the cross tie 3 performs the function of stiffening the car transversely and of forming abutments for each portion of the cope 6 and, in addition, acting through the brackets 12, 12, serves to stien and support the sloping bottom walls 11, 11 as wel] as providing the pivotal mountings for the doors 9, 9, and bearings for operating shafts 16, 16. The cross tie 3 is supported by the channels 5, 5, forming part of the center sill, so that the whole construction is sturdy and well adapted to withstand the shocks encountered in service.

Though a preferred embodiment of the present invention has been described in dctail, it is to be understood that many modiications may be made without departing from the spirit ot' the invention. lt .is intended in this patent therefore to cover all such modilications that fall within the scope ot' the appended claims.

What is claimed is:

l. Dump car construction comprising longitudinally extending' strengthening means, a cross tie mounted above said strengthening means and cope means mounted above said strengthening .means and abutting said cross tie on the two sides thereof for caus` ing the shedding of lading laterally ot' said strengthei'iing means.

2. A dump car, comprising a pair ot' longitudinally extending hopper portions, longitudinally extending strengthening means between said hopper portions, said strengthening means comprising channel members spaced apart, a cross tie mounted above said channel members, and cope means mounted above said channel members on the two sides of said cross tie 'for shedding lading to the two sides of said strengthening means.

3. A dump car comprising a pair ot' longitudinally extendng hopper portions, strengthening means provided between said hopper portions, said strengthening` means including a pair of channels spaced part, a cross tie mounted above said channels and cope means forming part of said strengthening means occupying a position above said channels and abutting the two sides of said cross tie.

4. Dump car construction, including a pair of dump doors for center' dumping,

said dump doors having intermediate doors for side dumping, a center sill extending longitudinally ot the car, said center sill including spaced channels, a cross tie supported above said channels, said center sill including lading shedding means mounted above said .channels and abutting said cross tie on the two sides thereof, sloping side walls adjacent to said dump doors, and bracket means supported by said cross tie tor supporting said sloping walls, for providing a pivotal mounting 'for said dump doors, and for providing bearings for said intermediate doors.

5. A dump car comprising a center sill made up otl spaced channel members, a cope means above said channel members, a cross tie mounted upon the said channel members, said cope means being mounted to abut the two sides ot said cross tie, and means for securing said cope means to said cross tie to provide a rugged contraction.

6. Dump car construction, including a pair of dump doors for center dumping, a .center sill extending' longitudinally orn the car, said center sill including spaced channels, a cross tie supported by said channels, said center sill including lading shedding means mounted above said channels and abutting said cross tie on the two sides thereof, sloping side walls adjacent to said dump doors, and bracket means supported by said cross tie for supporting said sloping walls and Jfor providing a pivotal. mounting 'for said dump doors.
